1. Overview
Interrupt
Interrupt controller (ICUb)
Interrupt vectors: 256
External interrupts: 7 (NMI, IRQ0 to IRQ5 pins)
Non-maskable interrupts: 5 (NMI pin, oscillation stop detection interrupt, voltage monitoring 1
interrupt, voltage monitoring 2 interrupt, and IWDT interrupt)
16 levels specifiable for the order of priority
DMA
Data transfer controller
(DTCb)
Transfer modes: Normal transfer, repeat transfer, and block transfer
Activation sources: External interrupts and interrupt requests from peripheral functions
Sequence transfer
I/O ports
General I/O ports
48-/32-pin
I/O: 38/22
Input: 1/1
Pull-up resistors: 38/22
Open-drain outputs: 30/18
5-V tolerance: 2/2
Multi-function pin controller (MPC)
Capable of selecting the input/output function from multiple pins
Timers
Multi-function timer pulse
unit 3 (MTU3c)
6 units (16 bis × 6 channels)
Provides up to 16 pulse-input/output lines and three pulse-input lines
Select from among fourteen counter-input clock signals for each channel (PCLK/1, PCLK/2, PCLK/4,
PCLK/8, PCLK/16, PCLK/32, PCLK/64, PCLK/256, PCLK/1024, MTCLKA, MTCLKB, MTCLKC,
MTCLKD, MTIOC1A) other than channel 1/3/4, for which only eleven signals are available, channel 2
for 12, channel 5 for 10
26 output compare/input capture registers
Counter clear operation (with compare match- or input capture-sourced simultaneous counter clear
capability)
Simultaneous writing to multiple timer counters (TCNT)
Simultaneous register input/output by synchronous counter operation
Buffer operation
Cascaded operation
28 interrupt sources
Automatic transfer of register data
Pulse output modes: Toggle/PWM/complementary PWM/reset-synchronized PWM
Complementary PWM output mode
3-phase non-overlapping waveform output for inverter control
Automatic dead time setting
Adjustable PWM duty cycle: from 0 to 100%
A/D conversion request delaying function
Interrupt at crest/trough can be skipped
Double buffer function
Reset-synchronized PWM mode
Outputs three phases each for positive and negative PWM waveforms in user-specified duty cycle
Phase counting modes: 16-bit mode (channel 1 and 2)/32-bit mode (channel 1 and 2)
Dead time compensation counter function
A/D converter start trigger can be generated
A/D converter start triggers can be skipped
Signals from the input capture and external counter clock pins are input via a digital filter
Port output enable 3
(POE3C)
Controls the high-impedance state of the MTU’s waveform output pins
Compare match timer
(CMT)
(16 bits × 2 channels) × 1 units
Select from among four clock signals (PCLK/8, PCLK/32, PCLK/128, PCLK/512)
Independent watchdog
timer (IWDTa)
14 bits × 1 channel
Count clock: Dedicated low-speed on-chip oscillator for the IWDT
Frequency divided by 1, 16, 32, 64, 128, or 256
